IMPROVEMENT IN SEUTTLES PGR LMS,

KNOW ALL MEN BY THESE PRESENTS:

That I, E. CROSS, of Southbridge, in the county of Worcester, andCommonwealth of Massachusetts, have invented certain new and usefulImprovements in Shuttles forV Powerfiooms; and I do herebyr declare thatthe following is a full, clear, and exact description ci the same,reference being had tothe eccompanying` drawings, forming a part of thisspecification, and in which* i Figure 1 represents a perspective view ofmy improved shuttle.

Figure 2 represents a longitudinal section of one end of the block as itappears in the process of menufacture, and

Figure 3 represents a similar section after the tip and the tip-shieldand ferrule have been applied to the end of the block, as will be fullyexplained hereafter.

To enable those skilled in the art to which my invention belongs to makeand use the seme, will proceed to describe it more in detail. i i

In the drawings, A represents the body ci' the shuttle, which may bemade in any of the well-known styles of manufacture, so far as relatesto the central portion of the shuttle, and also so far as the cop orbobbinholding device is concerned. Y i

My improvements have reference to the mode of holdingV an'dish'ieldingthe tip and compressing thc'woo'd about the shank of the tip; and myinvention consists, rst, in a peculiar combination of a metal-tip shieldWith the tip and end of the shuttle; and, second, in the peculiar formof construction oi' the shield, whereby is made to shield and hold thetip in place, while at the same time preventing the end of the shuttlefrom splitting outf, i

ln the construction of my shuttle, the block is-bored out at each end,as seen at a, to receive the shankof the/tip B. A circuler groove, c, isthen cut in each e'nd of the block, leaving a core, d, between the holea 'and the groove c, upon which the tipi-shield C is driven, as sho-vnin iig. 3L As the tip-Shield C is contracted e.

little at the outer end, the core e? is compressed when the tip-shieldis driven on. Again, the.inner face or edge l of the shield is concave,so thatiwhen driven down it draws the ends oi' theA bres of the woodwhich form the bottom ofthe groove c in, as indicated in tig. 3. Theshield C may be driven 'on first, and then the stem ofthe tip driven in,or the shield may be driven part Way on and then the shank of the tipinserted and the tip driven down until it forces the shield to'itsposition shown in iig 3. After the tip and shields have been applied,as described, the ends ofthe shuttle are turnedoii, as shown in Hg. 1.

By my improvements the end ofthe shuttle-wood is prevented fromsplitting out, while the tip is held in l e very secure manner. Again,by constant use, the wood of the shuttle next to the tip is often Wornoi or broken away, so that the base of the tip has to be ground-cti` toprevent the breaking of the Warp-threads. Such grinding olf lof the baseof the tip, however, prevents its being used in the construction of newshuttles By the use f the shield C the tips are not ground 01T, thegrinding coming upon the shields, so that the tips een be usedin'several new Woods. v

Having described my improved shuttle, what I claim therein as new and ofmy invention, and desire to secure by Letters Patent, is l Thecombination, with the tip and Wood of the shuttle, of eninterposedshield, C, arranged, 'with relation to the tip .and theshuttlen'ood, substantially as'and for the purposes set forth.

. E. CROSS.
